Step-by-Step Solution

Solution:

Step 1: Understand key naming in ConfigMaps from files
When creating a ConfigMap from a file without specifying a key, the filename is used as the key.
Step 2: Apply to given filename
Since the file is named app.properties, the key inside the ConfigMap will be app.properties.
Final Answer:
app.properties -> Option C
Quick Check:
Filename = key name in ConfigMap [OK]

Quick Trick: Filename becomes key if no key specified [OK]

Common Mistakes:

Assuming ConfigMap name is the key
Using partial filename as key
Confusing key with ConfigMap name
